12 mm HDPE Tank Covers Manufacturer for Telecom And Network Cabinets

These HDPE tank covers are thick gauge vacuum formed parts supplied to drawing for telecom and network cabinets. They are formed from HDPE sheet at 12 mm, trimmed on 5-axis routers and inspected against the drawing before packing. Buyers choose this route where a metal fabrication is too heavy, or where injection moulding tooling cannot be justified for the volume.

Product specification

Key features

• One piece shell replaces a fabrication, so assembly hours drop
• HDPE keeps the weight down while stiffness is held through the formed shape
• Clear protective film finish as standard, further finishes on request
• Trimmed on 5-axis routers, so mounting holes and cut outs match the drawing
• Tooling stored against the part number for repeat and spare orders
• ISO 9001 quality system

Typical applications

• cable trays
• equipment shelves
• cabinet tops
• antenna radomes
• tank covers used across general telecom and network cabinets builds

How it is made

1. Parts are inspected, fitted with inserts or hardware if required, packed and shipped.
2. Tooling is cut: aluminium for production volumes, composite or printed moulds for samples and first articles.
3. The sheet is formed over the mould with vacuum and, where the draw is deep, with plug assist.
4. Drawings are reviewed and a manufacturability report is issued with wall thickness, draft and radii marked up.
5. The part cools on a jig so the shape is held while the material stabilises.

Material: HDPE

HDPE is chosen for chemical resistance and impact strength at low temperature. It needs more heat and a longer cooling cycle than ABS, and it is painted only after flame or plasma treatment.

Design notes

• add ribs or returns instead of increasing sheet thickness to save weight and cycle time
• plan the trim line on a flat face so the router can hold tolerance
• keep a draft angle of at least 3 degrees on vertical walls so the part releases cleanly
• avoid sharp steps in the mould, which show as chill marks on the finished surface

Finishing and assembly options

• clear protective film
• two coat polyurethane paint
• pad printed logos
• Threaded inserts, PEM fasteners and brackets fitted before dispatch
• Mating parts can be trial assembled before the first article ships

Quality

Sheet thickness is checked on the formed part at the points shown on the drawing, and the readings go into the report. Moulds, trim fixtures and programmes are stored against the part number, so a repeat order matches the first batch.

• ISO 9001 quality system
• UL94 V-0 grades available
• PPAP or ISIR on request

Packing and delivery

Each part is bagged, edges protected with foam, then cartonised for container loading. Standard lead time to first article is 3–4 weeks, and repeat releases ship against stored tooling without a new proving run.

Frequently asked questions

Are spare parts available later?

Tooling is stored against the part number for the life of the programme, so replacements or spare panels can be released at any time.

What quantity can I order?

Sample quantities start at one piece off printed tooling. The process pays back from about 25 pieces a year and runs well into several thousand.

Can you make it in another material?

Any grade in this family can be swapped in. Send the requirement and the material will be quoted with the price difference shown.
